First off what is MOA ive seen this a few times on this webpage. Also what would be a good rife to start long range shooting with. I am looking at the 308 because im 14 and dont want alot of kick. Also I was looking at single shots because they are cheaper. What would be a good scope to top it off with? I dont want to go to 1000 yard shooting comps yet just wanted to start around here in the fields at 2 and 300 yards. Dont really want to spend over 350 on the whole thing because I dont know if I like the sport yet.
